Twin-field quantum key distribution can overcome the secret key capacity of repeaterless
quantum key distribution via single-photon interference. However, to compensate for the …

Quantum key distribution (QKD) networks are promising to serve large numbers of users
with information-theoretic secure communication. In QKD networks, the detection-safe …

As a multi-particle entangled state, the Greenberger–Horne–Zeilinger (GHZ) state plays an
important role in quantum theory and applications. In this study, we propose a flexible multi …

Quantum key distribution (QKD) has been experimentally verified over fiber-based link.
However, it still remains problems to be solved. The key rate of QKD protocol naturally …

Semi-quantum key distribution is based on the basic principle of quantum mechanics, which
allows a classical user and quantum user to use information theory to have a secure shared …
